Dimensional Fund Advisors (DFA)
Investment Model Portfolios

Dimensional Fund Advisors (DFA) provides renowned low cost index funds to financial advisors. Unlike Vanguard funds, these funds are not directly accessible by retail investors.

This plan uses all of DFA funds as candidate funds. As for the redemption periods, the default 3 month minimum holding period is set to each of the DFA fund. DFA does not set an explicit minimum holding period requirement for their funds, though a general statement such as the following is provided in DFA fund prospectus.

POLICY REGARDING EXCESSIVE OR SHORT-TERM TRADING

The Portfolios are designed for long-term investors (except as described below) and are not intended for
investors that engage in excessive short-term trading activity that may be harmful to the Portfolios, including but
not limited to market timing. Short-term or excessive trading into and out of the Portfolios can disrupt portfolio
management strategies, harm performance and increase Portfolio expenses for all shareholders, including longterm
shareholders who do not generate these costs.

The Board of Directors of the Fund (the “Board”) has adopted a policy (the “Trading Policy”) and the
Advisor and DFA Securities LLC (collectively, “Dimensional”) and Dimensional’s agents have implemented the
following procedures, which are designed to discourage and prevent market timing or excessive short-term
trading in the Fund: (i) trade activity monitoring and purchase blocking procedures; and (ii) use of fair value
pricing.

The Fund, Dimensional and their agents monitor trades and flows of money in and out of the Portfolios from
time to time in an effort to detect excessive short-term trading activities, and for consistent enforcement of the
Trading Policy. The Fund reserves the right to take the actions necessary to stop excessive or disruptive trading
activities, including refusing or canceling purchase or exchange orders for any reason, without prior notice,
particularly purchase or exchange orders that the Fund believes are made on behalf of market timers. The Fund,
Dimensional and their agents reserve the right to restrict, refuse or cancel any purchase or exchange request made
by an investor indefinitely if the Fund or Dimensional believe that any combination of trading activity in the
accounts is potentially disruptive to a Portfolio. In making such judgments, the Fund and Dimensional seek to act
in a manner that is consistent with the interests of shareholders. For purposes of applying these procedures,
Dimensional may consider an investor’s trading history in the Portfolios, and accounts under common
ownership, influence or control.

In addition to the Fund’s general ability to restrict potentially disruptive trading activity as described above,
the Fund also has adopted purchase blocking procedures. Under the Fund’s purchase blocking procedures, where
an investor has engaged in any two purchases and two redemptions (including redemptions that are part of an
exchange transaction) in a Portfolio in any rolling 30 calendar day monitoring period (i.e., two “round trips”), the
Fund and Dimensional intend to block the investor from making any additional purchases in that Portfolio for 90
calendar days (a “purchase block”). If implemented, a purchase block will begin at some point after the
transaction that caused the investor to have engaged in the prohibited two round-trips is detected by the Fund,
Dimensional, or their agents. The Fund and Dimensional are permitted to implement a longer purchase block, or
permanently bar future purchases by an investor, if they determine that it is appropriate.
